Application filed December 1, 1928?. Serial No. 72,581.

My present invention relates to improvements in paper machines and particularly tal endless travelling screen or apron (called the wire) on one end of which the pulp is deposited for the formation of a layer or web,- and from the other end of which wire the web is continuously removed and carried away.

At the lateral edges of the web it is cnstomary to utilize endless deckle belts or edge belts which rest on the wire for the purpose of preventing the pulp from drop ing over the edges of the wire and for the ormation of the deckle edges of the web.

These belts are each supported on pulleys journaled above the wire in a deckle frame, and both the wire and the belts are subjected to wear resulting in constant repair and replacement of parts at a'considerable ex ense.

he primary object of my invention is the Z provision of an attachment for this type of machines (which is also applicable for use with various other types of machines) whereby the wear on the wire is diminished and the wirethus rendered more durable; and a stationary but adjustable edge-ruler or guide is substituted for the endless travelling edge belts, which guide-ruler, when WOIn may be readjusted, repaired, or replaced at comparatively low cost of material and labor without loss of valuable time due to an idle machine.

The invention consists essentially in combining with the. usual deckle frame or other part of the machine, a stationary, flexible,-

elastic and adjustable edge-ruler or guide at each edge of the wire and adapted to lightly contact with the upper face of the wire to prevent excessive lateratmo'vement of the pulp and to form the dcckle edge of the web, together with certain novel features of construction and arrangement,of -parts as will hereinafter be more fully set forth and claimed. r

In the accompanying drawings I have illustrated the complete examples of the wherein the parts are combined and arranged in accordance with the best modes I have thus far devised for the practical application of the principles of my'invention.

In carrying out my invention .machines now in use may'readily-be converted for the purpose by removing the usual endless deckle belt or guide belt and its supports and substituting the devicesof my inven-- tion, which are attached to the deckle frame now in use, and of course I contemplate utilizing the device of my invention as part of the equipment of new machines. l f

In order that the general arrangement and relation of parts may readily be understood I have shown in Figures 1 and 2 a well known type of paper making machine from which the usual endless belts or deckle guides have been removed and-replaced by" the devices of my invention. This machine; is of the Fourdrinier type having the usual supporting frame 1 and endless screen 2 made up of wire cloth in the form of an apron and hereinafter referred to as the wire,"which passes over the breast roll 3 and brass table rolls 4'which extend transversely of the machine beneath the working flight of the wire. The hearing or supporting bars 5 are indicated in Figure 1 for the table rolls, and the usual bottom guide rolls 6 and 7 are shown in this figure of the drawings, together with the drain tables 8, receptacles 9, and shower 10. The deckle frame Which is supported above the machine'directly over a part of the wire comprises a pair of longitudinally extending channel beams 11 which are joined by a transverse brace as 12, and other necessary accessories to form thecomplete frame. p

In equipping the paper making machine with my invention, I utilize apair ofdeckle bars as 13, one at each side of the wire and "attached beneath the channel bars 11 of the deckle frame by means of screws or bolts 14.

' rial may be used when suited for the purpose. The deckle bar is fashioned with a earin face 16 which extehds longitudinally of the er and is inclined at an angle to the perpendicular inner face of the deckle bar and by means of a retaining bar 17 the edge guide or ruler 15 is held against the smooth t bearing face with its lower edge in position to project over the edge of the wire 2 as indicated in Figure 3, for the purpose of guiding the phlp as it is formed into a web and preventing the pulp from dropping over the edge of the wire.

The retaining bar 17 is disposed at an angle to the guide-ruler and is preferably Y fashioned with a smooth rounded bearing,

face.18 that impinges against the flexible guide ruler to hold it in place. The guideruleris thus held by friction and its lower end rests lightly on the top surface of the wire 2. The edge ruler may with facility be accurately adjusted to position by first withdrawing the retaining bar and then moving the 'stri or edge-ruler 15 to its proper position. he edge ruler may subsequently be adjusted to compensate for wear thereon and it will be apparent that the strip may he slipped down its inclined bearing face 16 substantially the distance of the width of the strip above the bearing point 18 of the retaining bar, thus prolonging the life and durability of the edge 'ruler and economizing in use of material. Theadjustment when required may readily be made and requires a minimum of time and labor.

The retaining bar 17 is suspended parallel with the deckle bar at the outer side of the latter, by means of hangers 19 rigid with the bar, and the hangers are provided with perforated heads 20 through which the hinge rod 21 is passed and secured to theheads. The retaining bar and hangers, together with the hinge rod 21, thus form a rigid retaining frame for the guide-rulerand menace resilient means are utilized to hold the retaining ba'zr 17 against the guide ruler. For

this pur use I employ hinges 22 located at suitable intervals along the deckle bar and secured thereto by means of screws 23. The hinges are preferably located in-mortises in the uoper face of the deckle bar to insure a smooth face for contact with the lower face of the channel beam 11 of the deckle frame,

and the hinge rod 21 is preferably rigid with the hangers 19 and loose in the hinges.

A suitable number of flat resilient plates or leaf springs 24 are used for resiliently holding the retaining bar 17 against the guide ruler. These springs are also counter:

sunk in the upper face of the deckle bar-and secured therein by'screws 25, with thecurvcd metal plates located between the hinge rod 21 and the retainin bar, and with the lower ends of the springs caring against-the outer face of the retaining bar.

This construction it will be noted insures justing the two deckle guides or rulers 15' toward and from each other to adjust the rulers to a minimum or a maximum width of the sheet or pulp indicated as P. The deckling device is also sectionally adjustable with relation to the wire 2. For this purpose I employ a deckling frame comprising one or more units, depending upon the length of the deckle desiredand supported on and above the two side rails 26. Each unit comprises a pair of longitudinally extending parallel shafts 27, one at each side of the machine, and these shafts are journailed at their ends in duplicate bearing frames, one of which is indicated at the left side in Fig. 7 as a whole by the letter A and a complimentary bearing frame B is indi cated at the right in Fig. 7.- Two bear-in frames A are connected by a shaft 27 an two bearing frames B at the other side of the machine-are connected by a similar shaft 28. As the construction and operation of each of the four bearing frames included in a. unit are the same, a description of one device will sufiice for all of them. A

Each bearingframe' is provided with two slotted, vertical arms 28 and 29 supported from a base plate 30 by means of a spring passed bolt 31 passed through the plate and the latter is bolted securely on the upper face of the side rail 26.

These slotted plates have triangular upper portions with bearings 32 for the end lid of one shaft-27 and bearing 321 101: the end of another shaft-which latter bring is .used when a second'unit is em loyed. The two arms are fas ioned- -with"an inof which boss "extends transversely of the machine and is used to support a screw bar as 34 or 35. .This screw ar preferably is a cylindrical tube journalled in the bearing Figure 7.

boss 33, provided with exterior threads, and

the pair of screw bars 34 and 35 are axially,

alined and.

project-toward each other above the wire 2'. v

-A shaft'36-is secured in each tubular screw bar and a crank handle 37 is fixed at its end where it is'accessibie for use by anattendant of the machine. Shaft 36 has a bevel gear 38 thereon that meshes with a complementary gear 39 on shaft 27 and by turning the crank handle it will be apparent that a screw bar 34 in a pair of bearing frames as A-may simultaneously be turns I On each screw bar 34-35 is a travelling nut as 40 and 41 and each nut has an attaching flange 42 bolted on top of the deckle 8 a pair of screw bars 34 and a pair of screw bars 35' may be revolved when their respective crank handles 37 are turned for the purpose of moving or adjusting the deckle guides 15 and 15', laterally of the wire and relatively to one another. The range of lateral adjustment of the deckle guides is indicated betwwn the full line positions and the dotted line positions in The decklingdevice is also adjustable ver- 1 tically with relation to the wire 2v For this adjustment I use a pair of vertically disposed bolts 43 and is for each bearing frame A and B. These bolts are threaded through holes in the plates 28 and 29 of the bearing frames and at their lower ends rest upon the upper faces of the base plates 30. By turning the bolts the bear- --1ng framesA and B may be elevated or lowquite simple in construction, as it comprises a minimum number of parts that may readily be assembled, and as an attachment it may quickly be secured in operative position for use. A maximum wear may be sea cured from the flexible edge-rulers, and

when worn they may with facility be re-edjusted, and finally'replaced as required by new strips. The wear on the wire is negligible because of the light contact'therewith of the flerible elastic fore the durability 0 thus reducin .machine, an the guide-ruler performs its tegral bearing. boss 33 between them, thebore functions with accuracy and eihciency.

It will be noted that my improvement dispenses entirely with the present constrdction of deckle straps and becomes a part of the machine, being mounted upon or in proper relation to the pair of rails at one end of the machine, thus forming an actual or integral art of the machine.
